- Locating ground services
- Airports as unique environments l Risk analysis
Operatives and supervisors working in areas where there is a high risk of service strikes, particularly at airports.
At a major airport a subcontracting firm is engaged in drilling trial holes. Unfortunately neither the operative or his supervisor appreciates the importance of following the procedures. Below the surface lie gas pipes, pressur-ised fuel pipes, low and high voltage cables, telecoms services and fibre optics. The estimated cost of closing the airport due to a service strike is around £6million. The cost to the individuals of hitting a high-tension cable, however, could be much greater.
Neil: What are you doing here? Exactly.
Tony: I’m drilling some trial holes.
Tony: I was told to. It’s on the DAB sheet.
Neil: But what is the purpose of the job?
Tony: Er…find out what’s underneath.
Neil: Do you know what a PAS 128 is?
Tony: Is it an aircraft?
Neil: No it’s not a bloody aircraft!
Tony: Er….is it…..? (HE THINKS HARD)
Neil: Tell me how you surveyed this area.
Tony: I used the CAT.
Neil: And how effective is that through concrete?
Tony: Well it didn’t show up any cables or services.
Neil: Shouldn’t you be using GPR?
Tony: Er…Brian didn’t mention that..
Neil: Didn’t he?
Tony: But we did a proper toolbox talk and everything.
Neil: Do not do any more here – and especially no drilling.
Tony: I haven’t really started…
Neil: Any more lip and you won’t be working on this airport again. I’ll be back.
